Still trying it out unsure about if it works or not
I tried this on my husbands glasses and he still fogged up, I will try it again and see if we get better results. He snowmobiles a lot so hoping this works 😊
Nerdwax FogBlock
Bought Fog Block and Nerd cloth for my husband and myself for Christmas. Tested it out at going from super cold and rainy outside to the warm grocery store. Worked like a charm! First time I didn’t get fogged up by my mask ~ Yay! Thanks guys! 👍
I work outside and on cold days this really keeps my glasses from fogging up so I can do my job safely
